15Monitoring Airway Flow,
Volume and Pressure
The M1014A Spirometry Module is designed to be used in combination with Philips-branded airway
flow sensors and combined CO
2
/airway flow sensors. It produces a real time wave for flow, volume and
pressure of respiratory gases together with numerics for analysis of ventilatory mechanics.
The measurement provides:
• Airway flow, airway volume and airway pressure waveform.
•Numerics for:
– respiratory rate
–tidal volume
–minute volume
– PEEP (positive end-expiratory pressure)
– PIP (peak inspiration pressure)
– dynamic compliance
– airway resistance
• Numerics for: (only visible in Spirometry Values Window, no alarming, no trending)
– peak inspiratory flow
– peak expiratory flow
– negative inspiratory pressure
– mean airway pressure
–plateau pressure numeric
– I:E ratio
The measurement also provides pressure-volume loops, flow-volume loops and pressure-flow loops.
Please see the Respiratory Loops chapter for details on loops.
When using combined CO
2
/Flow sensors you can also perform mainstream capnography with
intubated adult, pediatric and neonatal patients. See the Measuring CO
2
chapter for details on the CO
2
measurement and the Accessories chapter for a list of compatible accessories.
WARNING Electrical Shock Hazard: Do not open the module. Contact with exposed electrical components may
cause electrical shock. Always turn off and remove power before cleaning the module. Refer servicing
to qualified service personnel.
